OTR stands for “off the record.” It’s a way to have encrypted private instant message conversations online. It uses end-to-end encryption so your network provider, government, and even the instant-messaging service itself can’t see the content of your messages.
Both Linux and the BSDs are free and open-source, Unix-like operating systems. They even use much of the same software — these operating systems have more things in common than they do differences. So why do they all exist?
Your phone just made a sound, but you’re busy using your PC. Do you pick up your phone, unlock it, and look at the notifications? Don’t bother — just have all your Android notifications appear on your computer.
Chromebooks locally sync some data, so you’ll want to wipe that personal data when selling or passing on your Chromebook. You can also reinstall Chrome OS — particularly useful if you’ve messed around in developer mode.

Sure, maybe your parents don’t need any help with their PC and your kids are better at technology than you are. But many geeks are called upon to be responsible for a relative’s PC — often after it breaks.
Linux isn’t the only alternative PC operating system out there. Some alternative operating systems are developed by large corporations, while others are small projects worked on by hobbyists.
Tools like ping, traceroute, lookup, whois, finger, netstat, ipconfig, and port scanners are available on nearly every operating system you can get your hands on. They’re used for everything from troubleshooting a connection to looking up information.
Microsoft added User Account Control to Windows in Windows Vista, and it’s still used on Windows 7 and 8 today. UAC restricts what programs can do without your permission.
Smartphones are expensive — you wouldn’t want to spend hundreds of dollars on one and end up with a scratched screen. Many people still buy screen protectors to protect those screens, but they’ve become less necessary.
You’ve probably seen references to TCP and UDP when setting up port-forwarding on a router or when configuring firewall software. These two protocols are used for different types of data.
Virtual machines are isolated containers, so the guest operating system in the virtual machine doesn’t have access to your computer’s file system. You’ll have to set up shared folders in a program like VirtualBox or VMware to share files.
Memory cards are used in digital cameras, music players, smartphones, tablets, and even laptops. But not all SD cards are created equal — there are different speed classes, physical sizes, and capacities to consider.
You can buy a laptop or Wi-Fi tablet and use it on Wi-Fi anywhere in the world, so why are cell phones and devices with mobile data not portable between different cellular networks in the same country?
Ubuntu 14.04 LTS will “form the basis of the first commercially available Ubuntu tablets,” according to Canonical. We installed Ubuntu Touch 14.04 on our own hardware to see what those tablets will be like.

Your operating system provides each user account with its own folders when you set up several different user accounts on the same computer. Shared folders allow you to share files between user accounts.
In 2012, Google’s Dianne Hackborn threatened to revoke CyanogenMod’s access to the Android Market if they moved forward with adding “Cornerstone” multitasking to their custom ROM. Samsung has since created their own multi-window multitasking feature.
Netbooks — small, cheap, slow laptops — were once very popular. They fell out of favor — people bought them because they seemed cheap and portable, but the actual experience was lackluster. Most netbooks now sit unused.
Web browser bookmarklets allow you to perform actions on the current page with just a click or tap. They’re a lightweight alternative to browser extensions. They even work on mobile browsers that don’t support traditional extensions.
Android still doesn’t offer proper multi-window multitasking, but you can get it with a third-party tweak. All you need is root access — you don’t have to install a custom ROM.
